When a private company owner goes through a separation or divorce, the tax implications can be significant and complex. Below are the key tax considerations that should be addressed to ensure an efficient and compliant division of assets and ongoing tax planning.
1. Division of Private Company Shares
- Equalization and Transfer of Shares: In most provinces, family law presumes an equal division of marital property, which includes shares of a private company acquired during the marriage. The transfer of shares between spouses or former spouses as part of a separation agreement or court order can generally be completed on a tax-deferred (rollover) basis under subsection 73(1) of the Income Tax Act (Canada) (the “Act”), provided both parties are Canadian residents at the time of transfer and the transfer is in settlement of rights arising from the marriage. The recipient spouse inherits the transferor’s adjusted cost base (ACB) and tax attributes, and no immediate capital gain or loss is realized unless the transferor elects out of the rollover.
- Valuation: The fair market value (FMV) of the shares must be determined for equalization purposes. This often requires a professional business valuation, especially if the company has significant retained earnings or goodwill.
- Shareholder Agreements: Review and, if necessary, update shareholder agreements to address the change in ownership and ensure that both parties’ rights and obligations are clear post-separation.
2. Tax-Deferred Reorganizations and Butterfly Transactions
- Corporate Reorganizations: If both spouses are shareholders and wish to separate their interests, a corporate reorganization (such as an estate freeze or a “butterfly” transaction) may be used to split the business into two separate entities. These transactions can often be structured on a tax-deferred basis if completed while the parties are still considered spouses under the Act. After divorce, more restrictive rules may apply, so timing is important.
3. Taxation of Support Payments
- Spousal Support: Ongoing periodic spousal support payments are generally deductible to the payer and taxable to the recipient, provided they are made under a court order or written agreement. Lump-sum payments, or payments not made on a periodic basis, are typically neither deductible nor taxable.
- Child Support: Child support payments are not deductible by the payer nor taxable to the recipient.
4. Attribution Rules
- Income and Capital Gains Attribution: Normally, income and capital gains from property transferred to a spouse are attributed back to the transferor. However, these rules cease to apply after divorce, and are suspended during periods when spouses are living separate and apart due to a breakdown in the marriage. A joint election can be filed to stop the attribution of capital gains and losses during separation.
5. Registered Plans and Other Assets
- RRSPs, RRIFs, TFSAs: Registered assets can be transferred between spouses on a tax-deferred basis if the transfer is made pursuant to a court order or written agreement relating to the division of property. For RRSPs and RRIFs, the transfer is direct and does not trigger tax at the time of transfer; tax is only paid when the recipient withdraws funds.
6. Principal Residence and Other Real Estate
- Principal Residence Exemption: If the family home is transferred as part of the settlement, the principal residence exemption may shelter accrued gains from tax. However, if there are multiple properties (e.g., a cottage), only one property per family unit can be designated as the principal residence for each year prior to separation. After separation, each former spouse can designate their own principal residence.
7. Legal and Accounting Fees
- Deductibility: Legal and accounting fees incurred to obtain or enforce support payments are generally deductible by the recipient. Fees related to the division of property or obtaining a divorce are not deductible.
8. Notification and Tax Filing
- Notifying CRA: It is important to notify the Canada Revenue Agency of a change in marital status within the required timeframe (after 90 days of separation or immediately after divorce) to ensure proper calculation of benefits and credits.
- Tax Credits and Benefits: Separation or divorce may affect eligibility for certain tax credits and benefits, such as the Canada Child Benefit, GST/HST credit, and the eligible dependant credit.
9. Planning and Professional Advice
- Valuation and Structuring: Engage qualified tax and legal professionals early to value business interests, structure settlements tax-efficiently, and ensure compliance with both tax and family law.
- Shareholder and Succession Planning: Update shareholder agreements and succession plans to reflect the new ownership structure and address future contingencies, such as death or disability of a shareholder.
Conclusion
The tax consequences of separation or divorce for private company owners are complex and require careful planning. Proper structuring of share transfers, support payments, and asset division can minimize tax exposure and avoid costly mistakes. Early professional advice is essential to achieve a fair and tax-efficient outcome.
